Hi, what do you want to do?
Curated OER
Reflection and Refraction
Life is only a reflection of what we allow ourselves to see. The lesson includes three experiments on light reflection, light refraction, projection, lenses, and optical systems. Each experiment builds off the ones before and...
Exploratorium
Cylindrical Mirror
Using flexible mirror-like paper, physical scientists experiment with images produced by curving it and looking into its reflective surface. They find that concave mirrors cause reflected light waves to cross and actually flip the image...
Exploratorium
Antigravity Mirror
Is it a bird? Is it a plane? It's super student! Physical science stars can fly during a unit on light as they see the reflection of one leg in a mirror, behind which the other holds them up.
It's About Time
Reflected Light
The lesson allows young scientists to use lasers and mirrors to study reflected light. A reading passage and homework question assess learning, while additional material introduces extension activities.
Exploratorium
Parabolas
A parabolic mirror toy demonstrates how concave mirrors objects reflect light and produce a realistic image at their focal point. This resource probably doesn't explain any more than the printed insert that accompanies such an apparatus...
Exploratorium
Touch the Spring
Concave mirrors and the images they produce are traditional topics in the physics classroom. This resource explains how to set up an investigation of them, and it provides you with the explanation of concepts.
Exploratorium
Vocal Visualizer
Make sound visible with an activity that provides directions for how to build a vocal visualizer meant to create light patterns. Making noise into the visualizer causes a mirror to vibrate, reflecting a laser beam, and creating...
Optical Society
Optical Society of America: Optics for Kids: Mirror, Mirror on the Wall
A simple experiment that clearly demonstrates angles of reflection when light hits a mirror. Accompanied by a good explanation of what's happening, and a link to an article on reflection.

Teach Engineering: Construct It!
Students use simple household materials, such as PVC piping and compact mirrors, to construct models of laser-based security systems. The protected object (a "mummified troll" or another treasure of your choosing) is placed "on display"...
Optical Society
Optical Society of America: Optics for Kids: Mirrors and Images
An experiment to investigate how many images appear as the angle between two hinged mirrors is increased. Accompanied by an explanation of what is happening, questions for students to consider, and a link to an article about reflection.
Exploratorium
Exploratorium: Science Snacks: Look Into Infinity
In this activity students will create images of images of images that can repeat forever. Students will recreate this effect by setting up two acrylic plastic mirrors.

Bill Nye: Pond, James Pond
Try this at-home science experiment to learn how to see through the mirror made by a pond's surface.
